Think twice about Wayland. It breaks everything!

Think twice before abandoning X11. Wayland breaks everything!

tl;dr: Wayland is not "the future", it is merely an incompatible alternative to the established standard with a different set of priorities and goals.

Wayland breaks everything! It is binary incompatible, provides no clear transition path with 1:1 replacements for everything in X11, and is even philosophically incompatible with X11.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating e

git clone into non-empty directory

Let's say you start a project locally, and do some editing.

$ mkdir -p ~/git/foo && cd ~/git/foo
$ touch NEWFILE

Now you decide you want to create a new github repo and track it, but the directory is non-empty so git won't let you clone into it. You can fix this, thusly:
